i wanted to ask abou this problem i have with tomcat...

I downloaded in for use in win98-SE, but everytime i start it up, nothing
happens.
I've tried tweaking the environment variables:
SET J2EE_HOME="C:\j2sdkee1.3.1\"
SET JAVA_HOME="C:\j2sdk1.4.0_02\"
SET CATALINA_HOME="C:\jakarta-tomcat-5.0.18"
SET TOMCAT_HOME="C:\jakarta-tomcat-3.3.1a"
SET ANT_HOME="C:\apache-ant-1.6.0"
SET CLASSPATH="%JAVA_HOME%\jre\lib\rt.jar;%J2EE_HOME%\lib\j2ee.jar"
SET PATH="C:\Program Files\Mts";"C:\j2sdk1.4.0_02\bin";"C:\j2sdkee1.3.1
\bin";"C:\apache-ant-1.6.0\bin";"C:\jakarta-tomcat-5.0.18\bin";"C:\jakarta-tomca\
t-3.3.1a\bin"
(i also have tomcat 3.3.1a on my pc, but i dont think its a problem since
whether or not its' there, tomcat 5.0.18 still wont work)

any ideas on how to solve this?
